組付、分解作業が非常に困難であるという欠点を有して
いた。In the rotary joint, one side of the relatively rotatable part is connected to the swivel base and the other side is connected to the truck side, and when the swivel base is rotated with respect to the truck, both joint parts are connected to the swivel base respectively. However, in order to prevent rotation of the rotary joint part on the dolly side, the rotary joint part on the dolly side and the dolly were conventionally fixed with bolts, etc. The problem is that the connection and fixing work using the bolts or the like must be performed in a very narrow space between the swivel tables, and it is very difficult to assemble and disassemble the rotary joint.

作業の能率向上を図れるようにすることを目的とする。The present invention eliminates the above-mentioned drawbacks and makes it possible to prevent or release the rotation of the rotary joint with respect to the trolley extremely easily and quickly, thereby improving the efficiency of assembly and disassembly work by workers. The purpose is to

旋回台側から係脱自在に構成しである事を特徴とする。That is, the present invention provides a rotor joint mounting structure for a work vehicle as described above, in which a locking piece for preventing rotation relative to the truck is provided on a rotary joint portion that rotates with respect to a rotary joint portion that is fixed to a rotating base. are arranged in series, and the locking piece is configured to be freely engageable and detachable from the swivel base side with respect to the engaging portion provided on the truck.

向上できるに至った。In other words, although it is possible to reliably prevent rotation of the rotary joint on the trolley side by the engagement between the locking piece and the engaging part, it is possible to prevent the rotation of the rotary joint from getting between the trolley and the swivel base when the rotary joint is installed or disassembled. Since the rotation of the rotary joint on the trolley side with respect to the trolley can be stopped and prevented from rotating without any trouble, the rotary joint can be assembled and disassembled easily, quickly and safely, greatly increasing work efficiency. We have been able to make significant improvements.
